HEXAMOL DINCH
Hexamoll DINCH is a versatile and phthalate-free plasticizer specifically developed for PVC and other polar polymers. With the chemical structure of 1,2-Cyclohexanedicarboxylic acid diisononyl ester, this product is a clear, colorless, and almost odorless liquid. It is particularly designed for sensitive applications requiring close contact with the human body.
Key Features and Application Areas
Hexamoll DINCH is soluble in conventional organic solvents and compatible with all monomeric plasticizers commonly used in the PVC industry. It is almost insoluble in water. The product is listed as suitable for food contact and medical applications (medical devices, blood bags, etc.). Its low viscosity and excellent cold resistance ensure ease of processing.

Storage and Handling
Hexamoll DINCH can be stored in normal carbon steel tanks (e.g., A 283 grade). However, if there are sensitive demands on product quality, storage in stainless steel (AISI TP 316 Ti) or aluminum (AlMg3) tanks is recommended. Protecting the product from atmospheric moisture is critical; otherwise, the water content may increase, or color changes due to rusting may be observed in normal steel tanks. Therefore, storage under a dry nitrogen blanket is advised. In its original packaging, protected from moisture and at temperatures below 40 °C, it can be stored for one year.
Frequently Asked Questions
Answer: Hexamoll DINCH is a phthalate-free plasticizer with an excellent toxicological profile. It is particularly preferred in safety-critical applications such as toys, food packaging, and medical devices.
Answer: Provided it is protected from moisture and stored at temperatures below 40 °C, it can be stored for 1 year in its original sealed packaging.
Answer: It is compatible with many polar polymers, especially PVC, and can be mixed with other monomeric plasticizers.
